Changes

The results indicate that for this strain of ''Brett'' a near equal cell density can be achieved with aerated or semi-aerated propagation while anaerobic incubation under agitation or still incubation resulted in less than half the cell density when compared to the former treatments. While the pH decreased with more aeration during propagation, it is interesting that the pH of all treatments were near equal by the end of the experiment. The cell counts reached by the aerobic and semi-aerobic treatments were much higher than I have seen reported in the literature and the time to reach maximum cell density is much shorter than previous reports for propagation of ''Brettanomyces''.
